Technical Specifications CR82 CINEMA SERIES

COMPONENTS & CONSTRUCTION

The CR82 two-way, passive, full range cinema surround loudspeaker system includes a 1.4-in exit compression driver mounted on EAW’s proprietary WGP® (Wave Guide Plate®) mounted coaxially within a 12-in cone transducer on a slanted baffle. The LF and HF sections are integrated with a complex, multicomponent passive crossover/filter network which tailors HF response to match the SMPTE/ISO 2969 response curve.

The enclosure is constructed of 3/4-in Medium Density Fiberboard (MDF). Extensive internal bracing is employed to minimize panel resonances resulting from the large acoustical energies generated within the enclosure while maximizing acoustical energy transfer into the audience area.

Input connectors, located on the top of the enclosure, are 2- terminal barrier strip, designed to accommodate bare wire, tinned leads or spade lugs. For safety, the black cloth grill is attached with multiple threaded fasteners.
